Fitting a Drop arm ball joint kit?

<< < (3/4) > >>

Les Henson:
You can apply moderate heat, but if you use too much it affects the structure of the metal and makes it weaker. You have to use common sense in this matter. Excessive heat/welding steering components is a big no-no as far as ther MOT and personal safety is concerned.

I've not had to remove the drop arm YET !!!!

why not ?
dont say it damages seals as ive never once damaged a seal  :shock:
and thats with oxyacetyline
careful use and common sense  :wink:  use a welding nozzle instead of cutting/heating torch

can apply heat accurately then and not everywhere


you can change a droparm ball joint in situe but its a pita and i prefere to remove

What would I know about doing my job.

As for heat on steering components.
The heat will cause the molecules in the metal to break up and could cause failure.
Of course like a lot of people you don't seem to be comcerned with saving lives.
How do you know if you've exceeded the A3+40 of the metal ???

The quote I gave was from a HUGE notice in the blacksmiths shop where I served my time.

As for removing the drop arm. I don't have either a hydraulic press or puller in my workshop and now that I no longer work I don't have access to those either. Still I can remove a drop arm without them.

extreme90:
apply pressure with puller, then apply the heat, rapid expansion with oxyacetyline will pop it off far sooner than applying a slow heat with a blow lamp which will then damage things

failures...never had one so cant effect it that much  :roll:

Range Rover Blues:
If you're going to get technical then the coefficient of thermal expansion for cast iron is about 1.2x0.000001 (ten to the power -6) per degree C

You barely need to get the thing warm to make a difference but mostly I find heat helps the WD40 do it's job.

Not they way I would do it.
I didn't mention the thermal expansion of any metal.
I posted the A3=40 which in the case I'm talking aboutr wouldn't even make the metal look hot. Nowhere near even starting to colour.
